Description

Einrichtung zur Regelung der Temperatur von überhitztem Wasserdampf. Die Regelung der Temperatur des überhitzten Wasserdampfes durch Einspritzen von Wasser ist bekannt, ebenso diejenige durch 1<-Iischen mit gesättigtem Wasserdampf. Das erste Verfahren hat bei den bisherigen Ausführungen den Nachteil, daß große Wassermengen eingespritzt und erwärmt werden müssen, während nur ein kleiner Teil des eingespritzten Wassers zur Verdampfung gelangt. Das zweite Verfahren hat den Nachteil, daß der Wärmeaustausch zwischen dem überhitzten Dampf und dem Wasser bzw. den im :gesättigten Dampf enthaltenen fein verteilten Wasserteilchen ein sehr schlechter ist und so überhitzter Dampf von sehr ungleichmäßiger Temperatur entsteht, der nicht frei von feinen Wasserteilchen ist. Außerdem bedarf es gerade wegen der schlechten. Wärmeübertragungsverhältnisse großer Räume für den Wärmeaustausch.Device for regulating the temperature of superheated steam. The regulation of the temperature of the superheated steam by injecting Water is known, as is that obtained by mixing with saturated water vapor. The first method has the disadvantage that large Amounts of water need to be injected and heated, while only a small part of the injected water evaporates. The second method has the Disadvantage that the heat exchange between the superheated steam and the water or the finely divided water particles contained in saturated steam are very bad is and so superheated steam of very uneven temperature that is not free from fine water particles. Besides, it just needs because of the bad. Heat transfer ratios of large rooms for heat exchange.

Diese Erfindung vermeidet die Nachteile, indem sie in einem Behälter den Wärmeaustausch zwischen Wasser und überhitztem Dampf unter Vermittlung von Körpern großer Oberfläche, wie Metallkugeln, Ringen o. dgl. bewirkt. Der hierdurch bewirkte Wärmeaustausch wird so intensiv gestaltet, daß es nur kleiner Räume bedarf und die Temperatur und Beschaffenheit des Dampfes nach der Regelung eine sehr gleichmäßige wird.This invention avoids the disadvantages by being in a container the heat exchange between water and superheated steam through the intermediary of bodies large surface, such as metal balls, rings or the like. Causes. Which caused it Heat exchange is designed so intensively that only small rooms are required and the The temperature and nature of the steam after the regulation are very uniform will.

Eine Ausführungsform der Einrichtung zeigt die Abbildung. In die von überhitztem Dampf durchströmte Rohrleitung a wird durch das Rohr b Wasser in möglichst fein verteilter Form eingespritzt. In einem oder mehreren Systemen von eingelegten Körpern c, wie z. B. Metallkugeln, Ringen u. dgl. wird auf diesen eine dünne Wasserhaut bei großer Fläche gebildet; zugleich entsteht durch die Querschnittsverengung die erforderliche hohe Dampfgeschwindigkeit. Im Rohrteil d befindet sich dann nur noch überhitzter Dampf, da die Systeme c so bemessen sind, daß alles Wasser verdampft wird. Der Dampf wird bei e abgezogen. Bei f befindet sich die Entwässerung beim Anlassen der Einrichtung.An embodiment of the device is shown in the figure. In the from superheated steam flowing through pipe a is through pipe b water in as possible finely divided form injected. In one or more systems of inserted Bodies c, such as B. metal balls, rings and the like. A thin water layer is on these formed with a large area; at the same time, the narrowing of the cross-section creates the required high steam speed. In the pipe part d is then only superheated steam, since the systems c are dimensioned in such a way that all water evaporates will. The steam is withdrawn at e. At f the drainage is at Starting the facility.

Zum selbsttätigen Betrieb der Einrichtung wird die Wasserzufuhr nach der Höhe der Temperatur des Dampfes im Rohr e eingestellt, indem dort ein Temperaturregler bekannter Bauart eingebaut wird.For automatic operation of the device, the water supply is after the height of the temperature of the steam in the tube e is set by a temperature controller there known design is installed.
